A supply of build material such as a spool or cartridge is instrumented with a data tag that includes information about the build material. A three-dimensional printer, or a tag reader in communication therewith (directly or indirectly), can read the information from the tag for a determination as to how to use the build material during fabrication of a three-dimensional object.

Tagged build material for three-dimensional printing

A supply of build material such as a spool or cartridge is instrumented with a data tag that includes information about the build material. A three-dimensional printer can read the information from the tag and determine how to use the build material during fabrication of a three-dimensional object.

A three-dimensional printer uses leveling screws with tactile feedback to assist a user in properly orienting a build platform within a working volume.

Build platform leveling with tactile feedback

A three-dimensional scanner uses a rotatable mounting structure to secure a laser line source in a manner that permits rotation of a projected laser line about an axis of the laser, along with movement of the laser through an arc in order to conveniently position and orient the resulting laser line. Where the laser scanner uses a turntable or the like, a progressive calibration scheme may be employed with a calibration fixture to calibrate a camera, a turntable, and a laser for coordinated use as a three-dimensional scanner. Finally, parameters for a scan may be automatically created to control, e.g., laser intensity and camera exposure based on characteristics of a scan subject such as surface characteristics or color gradient.

Laser scanning systems and methods

A variety of thermochromic build materials are disclosed for use in color-controlled three-dimensional printing. By providing materials that exhibit a final color dependent upon heat applied during a melt or extrusion process, objects can be fabricated having a user-controlled color that varies from object to object, or within a single object.

Thermochromic build materials

A variety of techniques for color mixing support a user-controllable palette of colors for use when fabricating three-dimensional objects.
